Introduction
As the name suggests, your starter motor plays an essential role in starting your car’s engine. If it fails, your car won’t start. Getting your start motor repaired can be time-consuming and pricey. To help you avoid big bills down the line, this guide will answer some key questions about starter motor maintenance and repair.
What is a starter motor?
A starter motor is an electric motor that initiates the engine. When you turn the key or press the start button, the starter motor engages the engine's flywheel and starts the combustion process. Small yet powerful, this little motor is essential for getting your vehicle running.
What causes the starter motor to need a repair?
Several factors can cause the starter motor to fail, and leave you needing a repair or replacement:
- Wear and tear: Over time, the starter motor’s components can wear out due to regular use.
- Electrical issues: Faulty wiring, blown fuses, or a weak battery can lead to starter motor problems. Poor connections can prevent the motor from receiving enough power.
- Mechanical failures: Problems with the starter solenoid, which engages the motor, or issues with the flywheel can cause the starter motor to fail.
- Environmental factors: Exposure to extreme temperatures and moisture can damage the starter motor and its connections.
Regular maintenance and checks can help correct many of these issues before they become a problem.
What are the signs of a faulty starter motor?
Recognising the signs of a failing starter motor can help you address problems early:
- Clicking noise: Hearing a clicking sound when you turn the key can indicate a problem.
- Engine not turning over: If the engine doesn’t crank, the starter motor might be faulty.
- Intermittent starting issues: Occasional failure to start, especially after the car has been running, can signal a starter motor issue.
- Grinding noise: A grinding sound can happen if the starter gear doesn’t engage properly with the flywheel.
- Smoke or burning smell: Overheating after trying to start the car several times can cause smoke or a burning odour.
If you notice these symptoms, it is crucial to get your starter motor checked by a professional.
How to test a starter motor
Working out the problem with a starter motor involves a few tests:
- Visual inspection: Check for visible signs of damage, such as corrosion, frayed wires, or loose connections.
- Battery check: Make sure the battery is fully charged and in good condition. A weak battery can mimic starter motor problems.
- Voltage test: Use a multimetre to measure the voltage at the starter motor terminals. The voltage should be close to the battery voltage.
- Starter solenoid test: Listen for a clicking sound from the solenoid. If there is no sound, the solenoid might be faulty.
- Current draw test: Measure the current draw when starting the engine. High or low current draw can indicate issues with the starter motor.
While it’s possible to inspect a starter motor yourself, for accurate results your best bet is to take your vehicle to a professional mechanic.
How long does a starter motor last?
The lifespan of a starter motor depends on several factors:
- Usage: Frequent short trips can reduce the starter motor’s lifespan due to repeated starting.
- Maintenance: Regular upkeep and timely repairs can extend the motor’s life.
- Quality: High-quality starter motors typically last longer than cheaper alternatives.
On average, a starter motor lasts between 100,000 to 150,000 miles.
How much does a starter motor repair cost?
The cost of repairing or replacing a starter motor will depend on a few different factors:
- Repair costs: Minor repairs, like replacing a solenoid or fixing wiring issues, will be cheaper than a full replacement.
- Replacement costs: Replacing a starter motor tends to range from £250 to £600, including parts and labour. The price depends on the car’s make and model and the type of starter motor.
Make sure you get detailed quotes from multiple mechanics to find the best deal.
Fixing starter motor issues as soon as you’re aware of them is essential for maintaining your vehicle’s reliability. If you notice signs of a failing starter motor, find a professional you trust to diagnose and fix the problem. If your vehicle won’t start and getting to a garage is a challenge, mobile mechanics offer convenient repair services, bringing the garage to you.
